GAS-HEATER.

Application led May 3,

To all whom t may concern.'

Be it known that I, BERNHARD COLUMBUS, a citizen of the United' States,residing in New York, county of Bronx, and State of New York, haveinvented certain new and useful Improvements in Gras-Heaters, of whichthe following is a specification.

My invention relates to an improved heater; particularly a gas heaterdesigned for attachment to an ordinary gas lighting fixture.

The primary object of my invention is to provide a gas heater of simpleconstruction and made up of parts that can very easily be assembled; thesaid parts being relatively in xpensive to produce, whereby the heatercan be made in large quantities at relatively low cost.

The above and other objects and advantages of my invention will beclearly lset forth in the following description, taken yin connectionwith the accompanying drawings, and the novel features of my improvedheater will be precisely defined in the appended claims, Thisdescription, however, is'explanatory only and I may of course makealterations in what is actually shown herein, especially as regardsmatters relating to the size, shape and arrangement of parts; to thefull extent indicated by the general meanings of the terms in which theclaims are expressed and by variations in the wording of the same.

On the drawings- Figure 1 is a side view partly in section showing myimproved heater mounted upon a gas fixture, and

Fig. 2 is a similar form of heater.

The same numerals identify the same parts throughout.

In the particular description of the drawings I use the numeral 1 inFig. 1 to indicate a burner, which carries a diffusion member comprisinga top 2 and a support 3, and adapted to be attached to the burner whenthe parts of the heater are assembled. The diffusion member is aiiixedtc one end of the burner 1 and the other end of this burner can beattached to a gas lighting fixture 4; having a threaded nipple 5. Theburner 1 includes a stem 6 having inside threads to enable it to bequickly screwed upon the fixture 4 when it is desired to put the heaterin position for use, When so mounted the heater will extend from theview showing another Specification of Letters Patent.

fixture +L upward and the top 2, which will be of large diameterrelative to the burner, will serve with the support 3 to diffuse theheat iny the usual manner.

The burner 1 is made 'up of a flaring section 7 c attached to ahemispherical or domeshaped section 8. Preferably the section 7 isintegral with the stem 6, and it is located at the end of the stemopposite the threaded end for engaging the nipple 5. rlhe section 7 hasa bead 9 extending around the rim of same and fitting into the adjacentend of the section 8 and sections 7 and 8 are united preferably byspinning or otherwise working the edge or rim l() of the section 8 overupon the bead 9; thereby making a beaded joint between the sections. Inthe section 8, just above this beaded joint, I provide plurality of jetopenings 11 which extend all `around the burner; and from the top ofthis section 8, which forms the upper portion of the burner, extends acylindrical projection, such as a boss 12. This cylindrical boss 12 isreceived in an opening at the center of the support 3, which thusengages it, and this boss is preferably made to lit the support tightly.

The edge ofthe top or deflector 2 is turned down as indicated at 13,giving this top the form of a dish shaped plate; and when the top 2 andburner 1 are united the down turned edge of the top 2 will beconsiderably higher than the jet openings 11. The utility of thisconstruction is due to the fact that the jets of burning gas issuingfrom the openings 11 and extending directly away from the burnernaturally tend to curl upward at'their outer ends, and' the currents ofheated air created by them flowing outward toward the rim of theimperforate top 2 are turned downward by the rim 13; and thus the heatof the burner is diffused evenly through the apartment.

The nipple 5 normally carries la short piece of tubing which has the gaslightingy tip on its outer end. In order to apply my heater it is onlynecessary to unscrew this section carrying the burner tip, remove it andapply the heater by screwing the stem 6 upon the nipple 5 as far as itwill go. rlhe usual ornamental collar 14 surrounding this nipple neednot be removed.

I prefer to give the support 3 the shape 'I of an inverted cone havingan opening at its apex to engage the boss 12. This cone may be made of asheet of metal, perfoy cia outward and upward.

rated or not, as desired, and it has projections 15 passing throughopenings 16 in the top 2, and then bent over, to lsecure it to the top.

I may also make the section 8 wit-h an outer circumferential shoulder17, serving as a seat for a coil of `wire 18, extending from theshoulder 17 up to the support 3.

This Wire assists in diffusing the heat fromv `portion 19, with jetopenings 11, and on accountof the sloping surface vof .the .portion 19,the Vjets at these openings will be .directed diagonally away from theburner, vor Above the `portion 19 the section 8 has inade fast thereto akcylindrical projection in the form .of a collar 20. Around `this collar`is placed the lower end of a cylindrical support 21, the supportengaging the collar and resting upon .the burner;`r and the support hasa cap 22 at its .upper end fastened by rivet 23 to the top This support2l may be perforated .or not, like the support 3.

It will be seen .that vthe construction of my improved heater is verysimple as allrof the parts can be stamped .out and made in one piece. Tounite the sections 7 and 8 only -a single operation is required and theburner andthe diffusion member can be secured to each other simply byfitting the support over the boss 12, or the collar 20, as the case maybe. This inode of assembling will hold` the burner and the diffusionmember to each other and if they come apart anyone can at once reunitethem. Of course if desired the support 3 may be soldered to the burneror positively secured thereto in any other convenient manner.

Though shown in vertical position as the The supports 3 and 21 arepreferably perforated to let air circulate therethrough and facilitatecombustion of the gas at the jet openings 11.

Having described my invention what I believe to be new and desire tosecure and protect by Letters Patent of the United States is:

1. In a gas heater, a Haring section having a stem and a hemispheric-alsection united .to the iaring section by a beaded joint, thehemispherical section having openings adjacent said joint .to providejets eX- tending directly away from said sections, a boss on thehemispherical section, a support having the shape of an inverted coneengaging said boss, a deiiector afliXed to the support, and .a wire,encircling the hemispherical section. Y

2. In a gas heater, aflaring section having a stem, and a hemisphericalsection united `to the flaring ysection by a beaded joint, thehemispher-ical section' having openings adj acent said joint to providejets extending directly away from said sections, a boss on thehemispherical section, a support having .the shape of an inverted coneengaging the boss, and an imperforate top having downturned edges, saidsupport having projections to yengage the top, and secure thesupport andthe top together. v

3. In a gas heater, a burner including a pair of sections united by abeaded joint, said sections each contracting away from said joint, oneof said sections having open-V ings therethrough to provide a pluralityof jets, a cylindrical projection .carried by said section, a perforatedsupport receiving said projection, and an imperforate .top havingdownturned edges afIiXed to said support.

In testimony whereof, I have signed my name to this specification thisV30th vday of April, 1918.

BERNHARD COLUMBUS.
